Loma Negra Compañía Industrial Argentina S.A. is Argentina’s leading cement producer, offering a comprehensive portfolio of building materials and construction solutions. The company operates a network of integrated cement plants, quarries and distribution centers across the country, supplying high-quality clinker, cement, concrete, mortar and lime products. With its headquarters in Buenos Aires and primary manufacturing facilities in San Juan, Olavarría, Zapala and Catamarca, Loma Negra plays a critical role in infrastructure, residential and industrial projects throughout Argentina.
Founded in 1926 by industrialist Alfredo Fortabat, Loma Negra has grown from a single cement plant in San Juan Province into a diversified construction-materials group. Over the decades, the company expanded its footprint through strategic acquisitions, including the Calera San Martín lime business and various aggregates operations. In 2016, Loma Negra became part of the InterCement Group, strengthening its access to global technologies, proprietary process improvements and sustainable manufacturing practices.
Today, Loma Negra’s product suite includes Portland cement, specialty cements, ready-mix concrete and pre-blended mortars, serving an array of end markets such as highways, bridges, residential complexes and industrial facilities. The company also produces quick-lime and hydrated lime under the Calera San Martín brand for steelmaking, environmental and agricultural applications. While its core market is domestic, Loma Negra maintains export channels to neighboring countries, including Uruguay, Paraguay and Chile, further diversifying its customer base and optimizing plant utilization.
Loma Negra is led by Chief Executive Officer José Manuel Capdevila, who heads a management team focused on operational excellence, cost efficiency and sustainability. Under his leadership, the company has implemented energy-saving initiatives, waste-heat recovery systems and alternative-fuel programs to reduce its environmental footprint. Through ongoing investments in plant modernization and digitalization, Loma Negra aims to bolster its competitive position, support Argentina’s construction industry and drive long-term value for its stakeholders.
